Description

The invention relates to a device for producing the pouch packaging and a pouch packaging according to the preamble of patent claim 2.

In such bag packaging, narrow side parts, which form the narrow sides in a filling area of the bag packaging, are folded over above the filling area in the direction of the respectively opposite narrow side and thus also form the upper side of the bag packaging.

Such a generic bag packaging in the form of a gusseted bag with a flat roof is from DE 196 12 102 C2 known. The patent specification EP 1 714 902 B1 of the applicant discloses another such bag packaging and a generic method for its production. The folded narrow side parts are formed into a round roof. A device for producing such a bag packaging with a rounded roof is also DE 10 2005 029 492 B4 refer to.

In all of the above-mentioned known bag packs, a U-shaped recess is provided between two bag flaps in the head area. The edges of the recess correspondingly have connecting seams arranged in a U-shape. The punching out or cutting out of the recess is cumbersome in terms of manufacturing technology and is therefore expensive.

The invention is based on the object of specifying a device for producing a packaging bag and a packaging bag, in which the production of the packaging bag is to be carried out with less effort and therefore more cost-effectively than known methods.

The invention solves this problem with a device according to patent claim 1 and with a bag packaging according to patent claim 2. Advantageous embodiments of the invention are specified in the dependent claims and in the following description. The device and the bag packaging can all be further developed with features that result from the description of only the method or only the device or only the bag packaging.

In a method for producing pouch packaging, in particular pouch packaging with a stand-up base, which has a filling area with a front side formed by a front long side part, with a rear side formed by a rear long side part, with a left narrow side formed by a left narrow side part and with a left narrow side formed by a right has a right narrow side formed with a narrow side part, the narrow side parts being narrower than the long side parts, and which has a head region which adjoins above the filling area and has an upper side which is formed by sections of the narrow side parts which are folded over in the direction of the respectively opposite narrow side, the side parts being arranged in this way that in the finished bag packaging, edge areas of the long side parts adjoining the narrow side parts in the head area are folded down to the middle of the respective narrow side part behind the narrow side parts, and the long side parts in the head area are connected to one another in a central area formed between the edge areas, it is essential to the invention that two incisions starting from the upper edge, parallel to each other and spaced apart from each other in the longitudinal direction of the bag packaging, are made in the middle areas of the long side parts, with a middle lip being formed by the long side parts between the incisions, which is used to connect the side parts that are already connected to one another at their edges in the longitudinal direction in the head area to one another, only transverse seals are introduced into the head region, of which at least one transverse seal is arranged in the middle area under the two incisions, and that the middle lip is folded over laterally over this transverse seal arranged in the middle area and is covered by the folded-over sections of the narrow side parts towards the top.

In pouch packaging, in particular pouch packaging with a stand-up base, which has a filling area with a front side formed by a front long side part, with a rear side formed by a rear long side part, with a left narrow side formed by a left narrow side part and with a right narrow side formed by a right narrow side part , wherein the narrow side parts are narrower than the long side parts, and which has a head area adjoining above the filling area with an upper side which is formed by sections of the narrow side parts folded over in the direction of the respectively opposite narrow side, edge areas of the long side parts adjoining the narrow side parts in the head area in each case are folded down to the middle of the respective narrow side part behind the narrow side parts and the long side parts are connected to one another in the head area in a central area formed between the edge areas, it is essential to the invention that the bag packaging is produced with the method according to the invention according to a possible embodiment, the pouch having two incisions made in the central portions of the long side portions starting from the top edge, parallel to and spaced apart in the longitudinal direction of the pouch and between which a central lip is formed by the long side portions, for connecting the longitudinal edges already formed at their edges side areas connected to each other in the head area only transverse seals are made in the head area, of which at least one transverse seal is arranged in the middle area under the two incisions, and the middle lip is folded over laterally over this transverse seal arranged in the middle area and covered by the folded sections of the narrow side parts to the top is.

The device according to the invention for producing a pouch packaging is set up to carry out all the steps of the method according to the invention, the device having a sealing tool which is set up to connect the side parts which are already connected to one another at their edges in the longitudinal direction to one another in the head area exclusively with transverse seals, and a integrated into the sealing tool or has a separate cutting tool, which is set up to produce the incisions in the head area of the pouch packaging to be produced exclusively in the longitudinal direction.

The pouch packaging is particularly suitable for holding small, powdery or liquid contents. The filling material is either a bulk material, such as coffee beans, tea leaves or coffee powder, or a liquid filling material, such as so-called “cold brew coffee” or another beverage. The bag packaging is preferably filled before the transverse seals are introduced in the head area and thus before the bag packaging is closed in the head area.

The pouch packaging is made, for example, from a section of tubular web, so that the side parts are connected to one another in one piece at their edges. However, additional longitudinal connecting seams can be provided between the side parts for greater stability of the bag packaging. As an alternative to the tubular track, a tubular connected flat track can be used. Alternatively, the bag packaging is formed from a prefabricated bag section. The prefabricated bag section preferably consists of a one-piece folded sheet that is folded over in the foot area, or of two or more than two folded sheets, or of sections of a gusseted tube. The prefabricated bag section has lateral folds with side folds, so that several prefabricated bag sections can be stored one on top of the other in a space-saving manner before they are filled. Optionally, connecting seams can also be provided in the middle of the narrow side parts in the longitudinal direction. The prefabricated bag sections are already closed at the bottom, in particular by means of a formed base. According to the invention, after the bag sections have been filled, the seals are applied in the head area. The incisions in the head area are made either together with the seals in the head area or alternatively already during the prefabrication of the bag sections.

The side folds that are optionally folded in, especially when manufacturing from prefabricated bag sections, are folded in between a front and a back, with the front and the back forming the long side parts for the bag packaging to be produced and the folded side folds forming the narrow side parts for the bag packaging to be produced after they have been unfolded.

The invention has recognized that the free space required to fold over the narrow side parts in the direction of the opposite narrow side in the head area can also be created by laterally folding over a middle lip and therefore no recess has to be made in the side parts from which the bag packaging is made.

The invention has also recognized that in order to fold over the middle lip, only two cuts in the longitudinal direction have to be made in the material, which is easier to implement in terms of production technology than additionally making cuts in the transverse direction or punching out the entire area exposed by the folded middle lip.

In addition, the invention has recognized that in order to connect the side parts in the head area, only transverse seals have to be provided. In particular, no longitudinal connections have to be provided next to the incisions. For this purpose, the transverse seals can reach below the incisions. In addition, the transverse seals next to the incisions can extend all the way or at least far to the upper edge of the bag flaps, that is to say they can be wide.

Furthermore, the invention has recognized that the transverse seals and the incisions can only be made in one step in the longitudinal direction, approximately in the same way as the known Euro perforation in the upper transverse seal of known bag packaging. The production according to the invention of the pouch packaging according to the invention is therefore greatly simplified. Alternatively, the incisions can be made beforehand, for example during the prefabrication of bag sections that are to be used for the production of the bag packaging.

In addition, the invention has recognized that the folded middle lip is arranged unobtrusively under the upper side of the pouch packaging and even reinforces it through the additional layers of material.

All transverse seals in the head area are particularly preferably designed as groove seals. A plurality of grooves are preferably provided one above the other. In sections, particularly in the area of a transverse seal to be opened for emptying the bag, only a single groove can be provided or the groove can be omitted.

Preferably, the section of a narrow side part folded over in the direction of the opposite narrow side is connected to the sections of the adjoining edge areas of the long side parts folded over behind this narrow side part up to below the incisions in the central area with a transverse seal designed as a groove seal of the transverse seals executed in the head area. In particular, exactly one groove or at least one groove below the incisions runs completely across the front long-side part and over the rear long-side part. In the edge areas, the long side parts are each connected to sections of the folded narrow side parts. The folded sections of the edge areas are not connected to each other.

The transverse seals designed as groove seals preferably also connect the long side parts to one another in the middle area between the incisions and the edge areas and thus replace a longitudinal connecting seam that is therefore not required here. A closed border is thus formed, which is preferably also used to form a pouring spout. In particular, it is provided that a pouring spout is formed from the section of a narrow side part folded over in the direction of the opposite narrow side together with the sections of the adjacent edge regions of the long side parts folded over behind this narrow side part. In a particular embodiment, the long side parts are not connected to one another in the central area between the incision facing the pouring spout and the edge area forming the pouring spout, resulting in an opening to the pouring spout similar to a vertical incision. Alternatively or additionally, in a further special embodiment, additional vertical incisions are provided in the pouring spout, in particular between the long side parts and the narrow side part.

In an advantageous embodiment of the pouring spout, it is provided that the pouring spout is closed with part of the transverse seal. In this case, this part of the transverse seal is preferably formed with only a single crease. A micro-perforated horizontal tear line or a cutting line is optionally provided below the transverse seal. Alternatively, the spout is set up for peeling and the transverse seal is designed for this purpose. Alternatively, the pouring mouth remains open or is only closed at its upper edge by means of a closing seam. According to a further alternative, the pouring spout is resealed, for example in the form of a clip seam. The pouring mouth either remains open over the reclosure or is closed with a closing seam. In a further alternative embodiment, the pouring spout has a screw cap.

In another advantageous embodiment, the pouch packaging is equipped with a pouch closure. It is provided in particular that an end section of the pouring spout is folded onto an end section of the other narrow side part, which is folded over together with the sections of the adjacent edge regions of the long side parts folded behind the other narrow side part. The upper end of the pouring spout is preferably placed on the upper end of a recessed grip. Furthermore, it is preferably provided that a bag closure, in particular with two deformable wires, is integrated into this end section of the other narrow side part, with which the recessed grip is formed in particular, the ends of which protrude beyond the other narrow side part, with which the pouring spout is formed in particular Grasp the pouring spout and clamp the pouring spout closed against the end section of the other narrow side part, with which the recessed grip is formed in particular.

According to one embodiment of the invention, the sections of the narrow side parts folded over in the head area in the direction of the respective opposite narrow side form a flat roof which is aligned perpendicularly to the sides in the filling area and adjoins the filling area. The pouch packaging produced in this way can be stacked to save space.

According to an alternative and particularly preferred embodiment to the embodiment with the flat roof, it is provided that the sections of the narrow side parts folded over in the head area in the direction of the respectively opposite narrow side have a substantially arcuate full round roof is formed, with the central areas of the long side parts in the head area running diagonally to the connecting transverse seal and form presentation areas for product information. Sections of the rounded roof can also be flat, for example in a middle section arranged above the middle lip. The particular advantage here is that the bag packaging shaped in this way is noticeable, is perceived as being of high quality and, in particular in connection with the pouring spout, can be advantageously gripped when pouring out the contents.

Particularly preferred in the embodiment with the rounded roof, it is provided that a recessed grip is formed from the section of a narrow side part folded over in the direction of the opposite narrow side together with the sections of the adjacent edge regions of the long side parts folded over behind this narrow side part. The recessed grip preferably does not provide a filling space connected to the filling area, but is separated from the filling area by the transverse seal.

In an advantageous embodiment, the transverse seal is implemented as a step seal, which reaches deeper under the center lip than in the adjacent edge areas in the direction of the filling area of the pouch packaging. This particularly supports the shaping of the round roof.

To further stabilize the rounded roof, a molded insert part made of plastic or cardboard that is essentially arched in shape is preferably arranged at least mainly under the rounded roof. The molded insert rests in particular on the middle lip. Alternatively, that is to say in the case of a pouch packaging without an insert molding, a section of the long side, which is folded over on the rear side of a narrow side that has been folded over and points to the top, is preferably fixed to the middle lip. The pouch packaging can optionally be designed with a flat roof or with a rounded roof. The middle lip is either folded over with both layers to one side, in particular to the back of the pouch packaging. Alternatively, the plies of the center lip are folded to opposite sides.

In a further advantageous embodiment of the method according to the invention, it is provided that to determine a desired height from which the side parts form the head area and to stabilize the shape of the filling area below this desired height, a fixation, in particular in the form of a the respective long side part with the point seal connecting the respective narrow side part, is provided at the desired height in the region of each edge at which the long side parts are connected to the narrow side parts.

As a result, the height down to which the head region extends can be set independently of the actual filling level, ie from which the side parts at least partially collapse and form part of the upper side of the pouch packaging. The fixings stabilize the side walls to such an extent that the pouch packaging retains its shape with an essentially rectangular cross section even above the actual level up to the fixings. As a result, the upper side of the pouch packaging then also retains its desired shape, for example the shape of a round roof with a desired curvature of the narrow side parts forming the upper side.

In a further embodiment of the invention, a horizontal incision is provided in the middle area, starting from the vertical incision at its lower end in the direction of the edge area forming the pouring spout. A recessed grip flag can be inserted and locked in this horizontal incision. The recessed grip lug consists of the section of the narrow side part folded over in the direction of the opposite narrow side together with the sections of the adjacent edge regions of the long side parts folded over behind this narrow side part, which together also form the recessed grip. Indirectly, this also makes it possible to lock a center lip tab, which is formed from the sections of the long side parts that form the center lip. The horizontal incision, which goes through both long side parts, is preferably already formed during or after the prefabrication of bag sections, in particular in the form of two individual incisions that are made separately or together in the two long side parts.

The pouch packaging is preferably a stand-up pouch. To form the stand-up base, a stand-up base aligned perpendicularly to the long sides and the narrow sides of the pouch packaging is folded from lower sections of the long-side parts and the narrow-side parts.

In the 1 and 2 a blank for a pouch packaging according to the invention is shown in the form of a stand-up pouch. The same reference symbols designate the same or corresponding parts in all figures. The raw piece is a prefabricated bag section, has gussets and is formed, for example, from a section of a gusseted tube or a flat web folded and connected in the form of a tube or from a number of individual parts connected to one another or a folded sheet. Alternatively, the bag packaging is formed directly from a tubular web or from a flat web, the side edges of which are first connected to one another. After a standing base has been formed, the pouch packaging is then filled and subsequently sealed in the top area.

The blank has a front long side part 1, an in 1 concealed behind the front long side part 1 arranged rear long side part 2 and laterally folded between the long side parts 1 and 2, a left narrow side part 3 and a right narrow side part 4. The left narrow side part 3 is folded and therefore arranged in two layers between the left edge regions 5 and 6 of the long side parts 1 and 2 . The right-hand narrow-side part 4 is also folded and is therefore arranged in two layers between the right-hand edge regions 7 and 8 of the long-side parts 1 and 2 . In a center region 9 of the front long side part 1 located between the edge regions 5 and 7 and a center region 10 of the rear long side part 2 located between the edge regions 6 and 8, the long side parts 1 and 2 rest directly against one another. The edges, in which the long-side parts 1 and 2 are connected to the narrow-side parts 3 and 4, are reinforced by means of sealing seams for better stability of the pouch packaging to be produced. Alternatively, the sealed seams on the edges can also be omitted. Fixings, in particular in the form of point seals, are then preferably provided on the side edges at the level of the transition between the head area and the filling area, in order to fix this level independently of the actual filling level in the filling area and to prevent an unwanted increase in the head area down to the actual filling level counteract deformation of the roof.

In the longitudinal direction, a section of the raw piece and thus of the side parts 1 to 4 are assigned to a head area 12, a filling area 13 and a foot area 14 of the pouch packaging to be produced. At the lower end of the foot area 14, all layers of the side parts 1 to 4 arranged one above the other are connected to one another by means of a sealed seam. A standing base is folded from the foot area 14 . The filling area 13 arranged above it has an approximately rectangular cross-section in the finished bag packaging and, when filled, completely or mainly takes a small-sized or powdery bulk material, such as coffee beans or coffee powder, or a liquid filling material, such as cold coffee, in particular so-called “cold brew coffee”, on. In the top area 12 of the pouch packaging, the cross section is narrowed compared to the filling area. Depending on the configuration, the head area 13 can also be partly filled with the bulk material.

In the head area 12, transverse seals 16, 17, 18, 19 and 20 are introduced into the blank for the production of the pouch packaging, which in the present case form a grooved seal designed as a step seal with grooves arranged transversely. The transverse seal 16 connects the long side parts 1 and 2 to one another in the central areas 9 and 10 . One half of the left narrow side part 3 is connected to the left edge area 5 of the front long side part 1 by means of the transverse seal 17 and to the left edge area 6 of the rear long side part 2 by means of the transverse seal 18 . Correspondingly, one half of the right narrow side part 4 is connected to the right edge area 7 of the rear long side part 2 by means of the transverse seal 19 and to the right edge area 8 of the rear long side part 2 by means of the transverse seal 20 . When the transverse seals 17 to 20 are made in one of the long side parts 1 and 2, either the other long side part 1 or 2 is folded over with the half of the respective narrow side part 3 or 4 that is not to be connected, so that the narrow side part 3 or 4 is or is unfolded while of the sealing, a layer in the form of a film or a lacquer is arranged between the halves of the left narrow side part 3 and the right narrow side part 4 that otherwise lie on top of one another, which prevents these halves lying on top of one another from being connected to one another during sealing.

Starting from the upper edge of the blank, two parallel incisions 23 and 24 are made in the central regions 9 and 16, which are at least partially connected to one another by means of the seal 16. The incisions 23 and 24 are thus oriented perpendicular to the grooves of the transverse seals 16-20. A region of the long side parts 1 and 2 arranged between the incisions 23 and 24 forms a middle lip 25 in the finished pouch packaging.

According to the method, the incisions 23 and 24 are made with a cutting tool. In this case, the cutting tool is preferably integrated into a sealing tool, which produces at least the transverse seals 16 to 20 . The production of the incisions 23 and 24 takes place in particular in accordance with the known production of a euro hole. The incisions 23 and 24 are in the 1 and 2 exaggeratedly broad for illustrative purposes. Preferably, however, no material is cut out of the long side parts 1 and 2 in the invention. In particular, no cut is necessary in the transverse direction and there is no waste. As an alternative to making the incisions 23 and 24 together with the transverse seals 16 to 20, the incisions are already made in the raw piece during the production of the bag sections, ie before the bag packaging is filled.

To support the formation of a rounded roof, the transverse seal 16 between the central regions 9 and 10 is deeper than would be necessary to seal the filling space from the incisions 23 and 24, and deeper than the transverse seals 17 to 20. The area of the side parts 1, 2 and 4, in which the transverse seals 19 and 20 and a part of the transverse seal 16 delimited by the incision 24 are introduced over a large area, forms a recessed grip 26 in the finished bag packaging, which is suitable for gripping the bag packaging, in particular when dumping bulk material. The area of the side parts 1, 2 and 3, in which the transverse seals 17 and 18 and a part of the transverse seal 16 delimited by the incision 23 are introduced, forms a pouring mouth 27 in the finished pouch packaging, through which bulk material is poured out of the pouch packaging can. In order to facilitate the opening of the pouring mouth 27, the transverse seals 17 and 18 are formed with only one groove or two grooves. Alternatively or additionally, in deviation from the exemplary embodiment shown, a reclosure for the reversible opening and closing of the pouring mouth 27 can be installed in the pouring mouth 27 .

3 Figure 12 shows the pouch 31 partially made from the blank with the base 32 folded from the foot portion 14 in a conventional manner. Alternatively, the base 32 could be formed with seals, cuts and folds corresponding to the top of the pouch 31 but flat.

For the further production of the pouch packaging 31, the narrow side parts 3 and 4 must also be completely unfolded in the head area. 3 shows the narrow side parts 3 and 4 already partially unfolded. The middle lip 25 is folded over laterally to the rear of the pouch packaging 31, so that a free space is created in the head region 12, which is laterally delimited by the incisions 23 and 24, into which the upper ends of the side parts 1 to 4 forming the recessed grip 26 and the pouring spout 27 can be inserted .

4 shows the finished pouch packaging 31. The narrow side parts 3 and 4 form a straight left narrow side 35 and a straight right narrow side 36 in the filling area. The upper side 38 of the pouch packaging 31 is formed by the upper sections of the narrow side parts 3 and 4 which are folded over in an approximately arc shape in the head region 12 . A section of the rear long side part 2 resting on the back of the folded right narrow side part 4 rests on the folded center lip 4 and is preferably connected to the center lip, for example by means of an adhesive bond. Sections of the long side parts 1 and 2 resting on the rear side of the folded left narrow side part 3 lie on end sections of the right narrow side part 4 . One end of the pouring spout 27 thus rests on one end of the recessed grip 26 and, in a further development of the exemplary embodiment shown, can be fixed to the recessed grip 26, for example by means of a reclosable sticker that is glued on.

Below the transverse seal 16, in the head area 12, sections of the long side parts 1 and 2 run diagonally to the filling area 13 and thus form presentation surfaces on the front side 39 and the rear side 40 of the bag packaging 31, which, due to their sloping position, often looks down from the bag packaging at an angle from above viewers are better turned towards and stand out.

5 shows the bag packaging 31 with the pouring spout 27 open. The pouring spout is for this 31 detached from the recessed grip 26 and erected. The transverse seals 17 and 18 are separated so that bulk material can be poured out of the filling space through the pouring spout 27 . For this purpose, the pouch packaging 31 can advantageously be gripped by the recessed grip 26 . Due to the possibility of being able to grasp the curved recessed grip 26 safely and optionally with only one hand, even when the bag packaging 31 is arranged inclined for pouring, the bag packaging 31 cannot unintentionally slip out of the grip. Safe pouring of the bulk material is possible. The pouring spout 27 can then be returned to the position shown in FIG 4 brought and thus closed. For a tighter closure, a reclosure can be incorporated into the pouring spout 27 in a further development of the illustrated embodiment.

6 shows a molded insert part 43, which is made of plastic, for example, and is adapted to the desired shape for the round base on the upper side 38 of the pouch packaging 31. The molded insert part 43 can be inserted above the center lip 25 and below the recessed grip 26 and the pouring mouth 27 and optionally connected to the center lip 25 and thereby partially enclose and overlap the recessed grip 26 with tongues 45 and 46 . Recesses 47 and 48 advantageously guide the edge areas 5 to 8 of the long side parts 1 and 2 and support the desired flat, sloping arrangement of the presentation area formed by the long side parts 1 and 2 in the head area 12. Either the pouch packaging already has the insert molding 43. Or the insert molding 43 is reused and set by the consumer after opening the bag package 31 .

7 discloses a bag package 1 according to another embodiment. In contrast to 4 is the bag packaging 1 according to in 7 illustrated embodiment equipped with a flat roof. The folding is basically the same here, but the filling area 13 extends to a height below the incisions 23 and 24, which is approximately half the width of the narrow side parts 3 and 4, i.e. half the distance between the long side parts 1 and 2 in the filling area 13 the filled pouch packaging 31 corresponds. The design of the head area 12 then corresponds to the design of the foot area 14 according to the end of the description 3 mentioned possible alternative embodiment of the standing base 32.

In all of the embodiments, the invention enables a particularly simple production of the pouch packaging 31 with the upper side 38 formed from narrow side parts 3 and 4.
